#DAC of CO2 from the atm. is being explored as a tech. that can contribute to the goal of reaching #NetZero CO2 emissions.

A new study led by @DonglongFu1 showed that the use of zeolitic materials are feasible for DAC when it is integrated with H2O harvesting.

"A combination of a commercially available desiccant, AQSOA-Z02A, and a mordenite-type zeolite (MOR) enables
continuous operation of a designed #DAC system comprised of two
parallel units with a regeneration temperature of 100°C," research finds.

Furthermore, "the system
using pure #zeolite alone requires regeneration at temperatures between 200°C and 300°C."

"Techno-economic analyses of 12 process
scenarios reveal that the energy requirement of the best scenario
investigated is 71 GJ/tCO2, while the conventional pure zeolitebased system requires 200 GJ/tCO2."

Research declared that, "the optimized system gives a
cost between $246 and $568 per ton CO2 #captured, depending on
the energy costs, while system operates at sub-0°C temperatures or with
integration of water harvesting, respectively."

🚨Scientists Make Strides in Resurrecting Woolly Mammoths to Combat Climate Change🚨

A pioneering biotech firm has successfully genetically modified mice, marking a key step toward developing mammoth-like elephants to restore Arctic ecosystems & slow permafrost thaw.🧵1/10 Colossal Biosciences (@colossal), a Texas-based biotech firm, has engineered mice with mammoth-like traits. Their ultimate goal? Create herds of cold-adapted elephants that could help protect permafrost and reduce carbon emissions.

3/Why does this matter for climate change?

Permafrost holds huge amounts of C. When it melts it emits CO2 & CH4—increasing global warming. Mammoths once maintained Arctic grasslands, which helped insulate the permafrost. Colossal wants to bring this process back via neo-mammoths

🚨The Big Green Button: Who Gets to Push It?

"Geoengineering isn't just a climate issue—it's a geopolitical chess game. Only US & China have power to unilaterally deploy #SAI at scale."

Will they race to control skies or seek climate diplomacy? New study explores 4 futures🧵1/9 Image
2/ SAI could cool the planet—but who controls it controls global climate security.

Key risks of unilateral deployment:
🔴 Termination shock
🔴 Environmental disruptions
🔴 SAI as a potential weapon
🔴 Geopolitical leverage—both a threat & opportunity Image
3/ This creates a security gap:

The US & China are locked in great power competition, yet neither has a clear strategy on SAI.

Who moves first? Who controls the stratosphere? The dilemma: Deploy & gain influence—or deter & risk falling behind? Image
